I don't claim any expertise on the subject of these pumps and sensors. I'm not an endocrinologist.

The Minimed doesn’t look like a true closed loop system. It warns the user of trends and levels, but user input (and in some cases, manual backup tests) must take place in order for it to meet a predicted need.

Of course as you suggested if the system goes haywire it could kill the patient.
